Hi,
I have tried to compile -rt3 patch for ppc (mpc8540ads) and it failed
with undefined referance errors on ppc/kernel/asm-offsets.c. Here is
the compiler outputs:

For a workaround to overcome this problem, I have applied below patch
to asm-offsets.c:

Then it failed again on asm/hw_irq.h because of syntax errors. Here is

Is a a compiler issue related to assembler (I'am currently using
gcc-4.0.0) or is this a bug?

Thanks alot.
Emin

2007/5/17, Ingo Molnar <mingo@xxxxxxx>:

i'm pleased to announce the v2.6.21-rt3 kernel, which can be downloaded
from the usual place:

http://redhat.com/~mingo/realtime-preempt/

more info about the -rt patchset can be found in the RT wiki:

http://rt.wiki.kernel.org

This is a fixes-only release assembled by Thomas Gleixner. Many PPC
fixes from Sergei Shtylyov, dynticks softirq fixes from Mikulas Patocka,
a CONFIG_IRQSOFF_TIMING fix from Daniel Walker and x86_64 hrt fixes from
Thomas Gleixner.

to build a 2.6.21-rt3 tree, the following patches should be applied:

http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.21.tar.bz2
http://redhat.com/~mingo/realtime-preempt/patch-2.6.21-rt3
